Claims.

This invention relates to an incendiary bomb scoop and more particularly to a manually operated heat insulated scoop provided with a hinged cover, adapted to be operated and controlled manually, and a long handle.

It is well known that incendiary bombs are capable of developing intense heat of a nature which would destroy ordinary materials. It has been suggested that these incendiary bombs be controlled by treatment with a fine spray of water. However, such treatment is not entirely satisfactory because some time elapses before the bomb can be placed under control and during this elapsed time considerable damage may have been effected. Attempts to dislooate a bomb from a vulnerable spot with ordinary means will result in the destruction of such means unless the same is capable of withstanding very high temperatures such as is developed by an incendiary bomb.

It is an object of the instant invention to provide an incendiary bomb dislocating means of an insulated scoop-like construction capable of actually picking up an incendiary bomb so that it may be carried to a relatively safe place.

It is a further object of the instant invention to provide an incendiary bomb handling means capable of maintaining and holding an incendiary bomb until it becomes dissipated.

Other objects and the nature and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawing, wherein:

Figure 1 is a view in perspective of an incendiary bomb in accordance with the invention with a portion of the cover of the scoop part broken away in order to disclose a portion of the interior thereof. An incendiary bomb is shown close to the scoop.

Figure 2 is a view similar to Fig. l. with the cover of the scoop in open position.

Figure .3 is a vertical sectional. viewof the scoop and a portion of the handle taken in a plane parallel to the axis of the handle but spaced therefrom so that a portion of the handle is shown in elevation. In this view the incendiary bomb is shown within the scoop. The lid is shown in solid lines in closed position and in dottedlines in open position.

Figure 4 is a fragmentary view in perspective of a modified form of control for the cover of the scoop.

Referring to Figs. 1-3 inclusive, the scoop Ill comprises a relatively long handle I l which may be made of wood or other suitable material and it may be generally cylindrical in shape. The lower end of the handle l2 cooperates with a socket l3 integral with or fixedly secured to the lower part or main portion of the scoop body I4 as best illustrated in Figure 3. Cooperating with the scoop body part I4 is the curved cover l5 provided with vertical sides it which cooperate in overlapping relation with the vertical sides I! of the scoop body part [4. Secured centrally of the cover I5 is the pierced angle bracket l8 to which is secured in pivotal relation the flexible operating rod I9. the lower end of which comprises a loop extending through the pierced angle bracket 8. The flexible operating rod l9 extends upwardly through the eyelets 20, 2! and 22 to its upper end 23 which is formed in the shape of a finger gripping ring 24. The eyelets 2|], 2| and 22 are secured to the upper side'of the rela tively long handle H.

The cover [5 comprises a top portion 25 of less dimension in the general direction of the axis of the handle than the length of the side 16 extending in the same direction so that the cover i5 may be opened to a relatively great extent as shown in the broken lines in Figure 3 without interference with the socket l3 or the handle H.

The metal bcdy'portion M and the metal cover 15 are provided on their entire interior surfaces,

with the exception of the interior of the sides 16 of the top IS, with a reinforced refractory relatively high heat resisting construction which comprises a layer of expanded metal lath 2% coated with a refractory cement 21 which may include such refractory materials as zirconium sand or calcium oxide or other refractory mediums and a suitable binder therefor so that the refractory medium may be applied in the form of a plaster or cement. The expanded reinforcing metal lath 26 is secured to the interior surfaces of the scoop body portion and cover by spot welding or the like.

In order to protect the edges or margins of the refractory medium from abrasion and the like, the margins of the exterior metal portions 28 are turned inwardly at 29 to form an acute angle as best shown in Fig. 3. The rear edge 30 of the cover l5 overlaps the forward edge 3! ofthe top of the body portion I4 as shown in Fig. 3 when the cover [5 is in closed position;

The cover I 5 is pivotally connected to the body portion I4 by the pintles 3?. which may be rivets or bolts or pins provided with suitable securing means at both inner and outer ends which do not interfere with the pivoting action of the cover. These pintles pass through the sides It of the cover I5 and the sides I! of the body portion I4.

In Figure 4 a modified form of control for the cover of the scoop is depicted. On the relatively long handle H is mounted a pierced guide bracket I02 through which passes the flexible operating rod II9. Secured to the operating rod H9 as by welding is a fixed washer or retaining means I03 against which the compression spring I04 is adapted to bear. At the opposite end the spring I04 bears against the lower side of the fixed bracket l 02 so that when the flexible operating rod H9 is drawn upwardly by pulling on the upwardly bent projection I05 against the action of the compression spring I04, the operating rod II9 may be locked in its upper position by lowering the catch lever I06 through the ring I24 formed integral with the operating rod H9. The catch lever I06 is pivotally mounted at Ill'I on the handle H0 and is provided at its opposite end with a trigger I08 which is normally held in its upper position by the small compression spring I 09 which is in a fixed socket. By pressing downwardly on the trigger I08 against the action of the spring I09, the catch lever I06 is forced upwardly and out of the ring I24 so that under the influence of the spring I04 the operating rod I I 9 moves downwardly until the upwardly extending projection I05 engages the upper face of the bracket I02 during which time the cover I5 will move from fully open position to fully closed position as shown in Fig. 3.

Whether the scoop is provided with operating means as shown in Fig. 1 or as shown in Fig. 4, the method of use of the scoop is substantially the same. The operator who is prepared to immediately seize the scoop from a convenient place upon receiving a signal that an incendiary bomb has been dropped on the users premises which may be a factory or school, a church or a hospital or some other vulnerable building, takes up the scoop by the handle which may be a relatively long rod of the dimension corresponding to seven feet or more, approaches the incendiary bomb B as shown in Fig. 1, pulls on the ring 24 so that the cover is in open position, scoops up the bomb Within the body portion I4 as shown in Figure 3 and then releases the ring 24 so that the cover I 5 may snap shut and trap the bomb B. The user may also approach the bomb with the cover in open position so that the forward movement of the scoop taken with the weight of the forward portion of the cover I5 will snap the scoop shut and trap the bomb B as shown in Figure 3. When using a scoop provided with the control shown in Fig. 4, the bomb may be approached with the scoop in open position so that it is only necessary to press the trigger I08 after the bomb B has been scooped up in order to release the cover I5 so that the scoop will be snapped shut by the action of the spring I04.

The scoop is intentionally not made airtight so that the gases emanating from the bomb B may be dissipated without injury to the scoop itself. The high heat resisting lining 'of the scoop protects the same from damage while the bomb is within the scoop and at the same time protects the user and others who may be about from particles which may fly from the bomb.

After the bomb has been scooped up with the utilization of the mechanism described, the bomb may be left within the scoop until it is dissipated or it may be transferred to a safe place and then the cover of the scoop may be opened so that the bomb may be deposited in said safe place where no destruction of valuable property or injury to persons may be accomplished by the bomb.

It will be obvious to those skilled in the art that various changes may be made in this device without departing from the spirit of the invention and therefore the invention is not'limited to what is shown in the drawing and described in the specification but only as indicated in the appended claims.
